[QUOTE]Originally posted by Mystery Solver: [QB] [QUOTE]Originally posted by Quetzalcoatl: OK I'll jump through the hoops.[/QUOTE]Perhaps, you're jumping the hoops too far, because... [QUOTE]posted by Quetzalcoatl: Nasidze, I., et al. 2006 The Gagauz, a Linguistic Enclave, are not a Genetic Isolate, [i]Annals of Human Genetics[/i] 71:379389 R1*-M173 Moldovians 0.0130 Gagauz 0.082 Turks 0.310 Ukranian 0.020 Hungarian 0.133 ******* underived M-45 in Eurasia Barac, L. et al. 2003 Y chromosomal heritage of Croatian population and its island isolates,[i] European Journal of Human Genetics[/i] 11: 535542 Y chromosome variation in 457 Croatian samples was studied using 16 SNPs/indel and eight STR loci. High frequency of haplogroup I in Croatian populations and the phylogeographic pattern in its background STR diversity over Europe make Adriatic coast one likely source of the recolonization of Europe following the Last Glacial Maximum. The higher frequency of I in the southern island populations is contrasted with higher frequency of group R1a chromosomes in the northern island of Krk and in the mainland. R1a frequency, while low in Greeks and Albanians, is highest in Polish, Ukrainian and Russian populations and could be a sign of the Slavic impact in the Balkan region. Haplogroups J, G and E that can be related to the spread of farming characterize the minor part (12.5%) of the Croatian paternal lineages. In one of the southern island (Hvar) populations, [b]we found a relatively high frequency (14%) of lineages belonging to P*(xM173) cluster,[/b] which is unusual for European populations. Interestingly, the same population also harbored mitochondrial haplogroup F that is virtually absent in European populations indicating a connection with Central Asian populations, possibly the Avars.[/QUOTE]P*(xM173) simply means all P lineages excepting M173 derivatives, which brings me the question of where else undifferentiated M173 chromosomes have been located aside from N. Cameroon [most frequent], followed by Egypt, Jordan, and Oman [much less frequent by comparison]. [QUOTE]Originally posted by Quetzalcoatl: underived M-89 in Eurasia Brion, M. et al. 2005. A collaborative study of the EDNAP group regarding Y-chromosome binary polymorphism analysis, [I]Forensic Science International [I]153 (2-3):103-108 Abstract A collaborative study was carried out by the European DNA Profiling Group (EDNAP) in order to evaluate the performance of Y-chromosome binary polymorphism analysis in different European laboratories. Four blood samples were sent to the laboratories, to be analysed for 11 Y-chromosome single nucleotide polymorphisms (SNPs): SRY-1532, M40, M35, M213, M9, 92R7, M17, P25, M18, M153 and M167. All the labs were also asked to submit a population study including these markers. All participating laboratories reported the same results, indicating the reproducibility and robustness of Y-chromosome SNP typing. A total of 535 samples from six different European populations were also analysed. In Galicia (NW Spain) and Belgium, the most frequent haplogroup was R1b*(xR1b1,R1b3df). [b]Haplogroup F*(xK) is one of the most frequent in Austria and Denmark, while the lowest frequency appear in Belgium[/b]. Haplogroup frequencies found in this collaborative study were compared with previously published European Y-chromosome haplogroup data.[/QUOTE]Again, R1b*(xR1b1, R1b3df) translates into R1b lineages barring the R1b1 and R1b3df lineages. F*(xK) similarly applies to all F derived lineages barring the K derivative(s). [QUOTE]Originally posted by Quetzalcoatl: Now please provide me some population examples in Africa of the underived precursors to R1*=M173[/QUOTE]Why? The focus at hand is rare undifferentiated R1*-M173 chromosomes in Africa. [/QB][/QUOTE]
